2021年10月13日，由中国科学院等离子体物理研究所自主研制的聚变堆主机关键系统综合研究设施（CRAFT）项目材料综合性能研究平台200W@4.5K氦制冷机一次性调试成功。此套200W@4.5K氦制冷机是为超导材料、绝缘材料等研究提供冷量及液氦，能够运行在纯制冷模式、纯液化模式以及混合模式，满足材料性能综合研究平台低温测试的需求。低温工程与技术研究室历时一年的时间，完成了整机的设计、装配以及安装...
近日，中国科学院合肥物质科学研究院等离子体所CRAFT项目电源团队首次研发成功100kA的单体真空开关，并成功分断100kA直流回路，在世界高储能直流分断技术领域取得新的突破。
基于人工过零的直流回路分断技术承担着超导磁体失超保护的重任，是确保CRAFT项目磁体安全的重要防线。该项目直流回路电流达到100 kA（ITER最高69 kA），分断要求极为苛刻，需要满足高参数、高储能、高可靠性的“三高”要求。长期以来，相关技术由俄罗斯、欧盟等掌控，项目团队进行自主研制的难度和风险较大。
